Elections are a pretty multimedia event for me now. Certainly one TV channel is not enough. Even flicking is a bit limiting (you can, after all, only watch one thing at a time). So I do normally have a computer near at hand when an election is taking place.
Tonight, I think I will be pointing my browser at this. Via the ever wonderful TechPresident blog, here is the ultimate online tool for keeping up to date with the action. So bookmark the page and enjoy.
P.S. As an aside, even if the Presidential election is looking like it is going to go one way, there is the small matter of the House and the Senate to provide some excitement. The map will also give you info on all of those races.
